Unit 9.1: Introduction to Entropy
Justify the sign of entropy or relative entropy values by examining the
dispersal of states (number of microstates) and number of moles of gas
during a change.
-
Why does entropy increase when a liquid evaporates to form a gas?
-
Compare the entropy change of N2(g) + 3H2(g) → 2NH3(g) and explain the
sign of ∆S.
Discuss the impact of temperature on entropy.
- Why does entropy generally increase with temperature?
-
At what point does entropy increase most rapidly: low, moderate, or
high temperatures?
